COTTON-PRESS.

Specification of Letters Patent.

Patented Jan. 19, 18 15..

Application filed May 21, 1914. Serial No. 840,019.

To all whom it may concern Be it known that I, ALBERT L. TREESE, citizenof the United States, residing at Cushing, in the county of Payne andState of Oklahoma, have invented certain new and useful Improvements inCotton-Presses, of which the following is a specification, referencebeing had therein to the accompanylng drawing.

This invention relates to cotton presses of the type of which each has aplurality of rollers inclosing a cylindrical space in which acylindrical bale is formed. In presses of this type it is necessary forsome of the rollers to be movable to permit the bale to be disengaged;These movable rollers are usually mounted on a movable frame sectlon andthis section must be very firmly secured in place when the balingoperation is carried on.

The object of my invention is to provide in a press of the type abovereferred to improved means for locking the movable frame section and themovable rollers in their normal operative positions.

My improved features are well adapted for that shown and described in myPatent No. 980,706, dated January 3, 1911, and in the drawings, forpurposes of illustration, I have shown a press similar to that shown inthe said patent. I desire it to be understood, however, that myinvention is not limited to the exact construction shown, but may beused with other presses for which it is adapted.

Referring to the drawings, Figure 1 is an end view of a press embodyingthe inven' tion, the view being partly in section along the line 11 ofFig. 2; Fig. 2 is a plan View of the mechanism for controlling the opening and closing of the press, parts of the press being also shown insection along the line 2-2 of Fig. 1; Fig. 3 is a fragmentary side viewshowing the lower parts of the press and the locking devices; ig. 4 is afragmentary sectional view showing one of the locking device's; Fig. 5is a detail perspective view showing one of the elements of one of thelocking devices; Fig. 6 is a fragmentary view taken along the line 6-6of Fig. 2.

Referring to the drawings, the main frame elements of the press. Theseuse in connection with a press such as 1, 1 represent are positioned atthe ends and are secured to the base or foundation members 2, 2.

3, 3 are movable frame sections pivoted rispectlvely to the main framesections 1, 1 a

5, 5 are horizontal rollers mounted in the frame to inclose asubstantially cylindrical space. Some of these rollers are carried bythe fixed frame sections 1, 1 and others by the movable frame sections3, 3. Each roller g) carries a drive pinion 6, and all of the pinlonsnormally mesh with a central drive gear Twhich is connected to receivepower by means of a belt wheel 8. The belt wheel 8 and the gear wheel 7serve as driving mechanism for all of the rollers. It will be seen thatwhen the movable rollers are moved their pinions are disengaged from thegear 7, but will be immediately reengaged upon the return of the rollersto normal position.

For moving the movable sections 3, 3 of the frame each of them isconnected to a rack 9. Preferably, these racks are rigidly connected tothe respective sections and are curved to be concentric with the pivotalaxes of the sections at 4. 10, 10 are pinions mounted upon alongitudinal shaft 11 and engaging respectively with the said racks 9,9. The shaft 11 carries a worm wheel 12 which meshes with a Worm 13 on atransverse shaft 14. Mounted on the shaft 14: are friction disks 15, 15between which there is a cone friction driving pulley 16. The conepulley 16 is mounted on a shaft 17, which is driven by means of the belt18 and the belt wheel 19. The shaft 17 is provided at 20 with a bearingin an eccentrically mounted sleeve. This sleeve carries an arm 21 whichis connected to a hand lever 22 by means of a link 23. An operator, bymoving the lever 22, can rock the sleeve through which the shaft 17extends, and can in this way move the drive pulley 16 to the right or tothe left to bring it into engagement with one or the other of the twofriction disks 15, 15. it will be obvious that when one disk is engagedthe shaft 14 will be rotated in one direction, and that when the otherdisk is en gaged the shaft will be rotated in the other direction.

The worm and worm wheel 13 and 12 serve as locking means for preventingthe rotation of the shaft 11 by means of forces applied to the pinions10, 10. In this way the press is automatically locked closed against anysmall pressures tending to open it. But experience has demonstrated thatthe pressure in a press of this type when cotton is being baled is sogreat that it is not safe to place final reliance upon the relativelysmall teeth of the pinion and the rack. In order to relieve these smallteeth of the pressure incident to the operation of the press I haveprovided adjacent each pinion a large supplemental tooth 23. Preferably,as shown in Fig. 5, this tooth is formed integrally with the pinion, andI find it advantageous to construct it with an approximately spiraloutline, as indicated. Connected to each of the frame sections 3, 3 is adepending lug 2-1 adapted to be engaged by the tooth 23 when the framesections reach their normal positions. These large heavy teeth 23, 23,by their engagement with the lugs 24, 24, take the strain tending,during operation of the press, to move the sections 3, 3. The strain istransmitted to the shaft 11 and from the shaft is transmitted to theworm wheel 18 which automatically locks the shaft against rotation,and'hence automatically locks the press in closed position.

hat I claim is:

1. The combination in a cotton baling press of a plurality of rollersarranged to normally inclose a cylinder, a roller carrying frame havinga movable section by means of which some of the rollers can be movedoutof their normal positions, driving mechanism for the rollers, means formoving the said movable section out of and into normal position, and adevice supplemental to the moving means for locking the movable framesection in its normal operative position, the said device beingconnected to the moving means to be automatically moved into and out ofoperative position thereby.

2. The combination in a cotton baling press of a plurality of rollersarranged to normally inclose a cylinder, a roller carrying frame havinga movable section by means of which some of the rollers can be moved outof their normal positions, driving mechanism for the rollers, a rack connected wih the said movable section for moving it out of and into normalposition, a rotatable driving pinion engaging the rack, a toothrotatable with the pinion and supplemental to the teeth thereof, and alug connected with the movable frame section and positioned to beautomatically engaged by the rotatable supplemental tooth when themovable frame section is'in normal position.

8. The combination Copies of this patent may be obtained for in a cottonbaling.
